I've been trying the past 2-3 hours to get this working but I simply don't have enough knowledge of regex.
I'm trying to make an url shortener, so I want to point a url like domain.com/d5Ds93X to something like domain.com/view.php?s=d5Ds93X
I've been messing around with my .htaccess file and have this now:
RewriteEngine on
RewriteBase /
RewriteRule /(.*?)$ /view.php?s=$1 [L]
And that sort of works, it points to the right file but the string (d5Ds93X) isn't passed on. My view.php file looks like this (for testing purposes):
<?php
if (isset($_GET['s']) && ctype_alnum($_GET['s'])) {
echo $_GET['s'];
}
?>
When visiting the url I just get a blank page. But if I echo anything before the if rule it does get displayed so the page works just fine. Does the data of the GET even get passed on? Or should I add code that detects the data in the url?
Use it like this:
RewriteEngine on
RewriteBase /
# If the request is not for a valid directory
RewriteCond %{REQUEST_FILENAME} !-d
# If the request is not for a valid file
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^/?(.+)$ view.php?s=$1 [L,QSA]
Make leading slash optional so that rule works from .htaccess as well as from Apache config.
Also restrict rule to skip files and directories.

Well I'm havin trouble creating .htaccess, anyway I have categories in my menu for example test1,test2,test3 that are the names of a folders, and what I'm trying to do is to point the second parameter of the url to index.php, for example http://myapp/test1 I want to be able from the index.php to have $_GET['cat'] = test1 and so on..
Here's what I've tried so far and didn't work:
Options +FollowSymlinks
RewriteEngine on
RewriteRule ^(.*)/$ index.php?cat=$1 [NC,L]
Any help with this? Much appreciated.
Try removing the trailer / character from your rewrite rule. ^(.*)/$ matches any URL that ends in a / like http://myapp/test/. You are probably looking for ^(.*)$ or to strip any leading slash ^/(.*)$. Note though that if index.php is accessed directly via f.ex. http://myapp/index.php this would also match and rewrite to http://myapp/index.php?cat=index.php and any images wouldn't also be directly accesible. So you might want to add some RewriteCond that first checks if the requested URL is an existing file with RewriteCond %{REQUEST_FILENAME} !-f before the RedirectRule to rewrite the URL.
I've been trying to rewrite my URL's with a htaccess file.
My project is using my index.php as it's basic controller.
I fetch the pages from the database with the get-value "naam".
Example:
localhost/YourDesigns/YDCMS/index.php?naam=home (this shows the homepage)
localhost/YourDesigns/YDCMS/index.php?naam=about (this shows the about page)
Now i want to rewrite the URLS to be shown like this:
localhost/YourDesigns/YDCMS/home (this shows the homepage)
localhost/YourDesigns/YDCMS/about (this shows the about page)
I have done some htaccess stuff myself and i've successfully removed the "index.php" from the url, but the "naam" still remains.
How do i remove this?
This is my current htaccess file:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /YourDesigns/YDCMS/index.php?naam=/$1 [L]
Thanks in advance :)
I think your way to see the process it's not totally right, if you want to show the url like you say localhost/YourDesigns/YDCMS/home you have to first replace the url inside your html content to that format, then by using a RewriteRule you call the correct path internally:
RewriteRule ^desired_url_path/([a-z0-9\-]+)$ /base_url_path/index.php?naam=$1 [L]
this way when an user click on a link the Apache server will use the above regex to convert the url by a rule that basically says : everything after the base url is aparameter value to be passed on the index.php.
Naturally the regex can be modified to suit your needs, the one i've written above it's a basic string pattern.
I'm trying to convert a query string;
http://atwd/books/course?course_id=CC100&format=XML&submit=Submit
Into a segment URI;
http://atwd/books/course/CC100/XML
I'm working in CodeIgniter.
I was looking at a stackoverflow answer that said to check CodeIgniter's URL segment guide, but I don't think there's any information on how to convert a query string into a segment URI. There is, however a way to convert a segment URI into a query string, which is bringing up a load of results from Google too.
Following another stackoverflow answer, I tried this in my .htaccess file but nothing seemed to work
RewriteCond %{QUERY_STRING} ^course_id\=([^&]+)\&format\=([^&]+)$
RewriteRule ^$ /course/%1/format/%2 [R,L]
In my entire .htaccess file I have this;
<IfModule mod_rewrite.c>
RewriteEngine on
#Source: http://codeigniter.com/user_guide/general/urls.html
#Removal of index.php
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /index.php?route/$1 [L]
#Source: https://stackoverflow.com/questions/3420204/htaccess-get-url-to-uri-segments
#Format Course function requests
RewriteBase /
RewriteCond %{QUERY_STRING} ^course_id\=([^&]+)\&format\=([^&]+)$
RewriteRule ^$ /course/%1/format/%2 [R,L]
</IfModule>
This is in my root directory of Codeigniter screenshot
My code in the .htaccess file isn't working, I refresh the page and nothing happens. The code to hide the index.php is working though. Does anyone know why?
The notion of "converting URLs" from one thing to another is completely ambiguous, see the top part of this answer for an explanation of what happens to URLs when redirecting or rewriting: https://stackoverflow.com/a/11711948/851273
There's 2 things that happen, and I'm going to take a wild stab and guess that you want the 2nd thing, since you're complaining that refreshing the page doesn't do anything.
When you type http://atwd/books/course?course_id=CC100&format=XML&submit=Submit into your browser, this is the request URI that gets sent through mod_rewrite: /books/course. In your rule, you are matching against a blank URI: RewriteRule ^$ /course/%1/format/%2 [R,L]. That's the first reason your rule doesn't work. The second reason why it doesn't work is because above that, everything except images and index.php and robots.txt is being routed through index.php. So even if you were matching against the right URI, it gets routed before your rule even gets to do anything.
You need to correct the pattern in your rule to match the URI that you expect to redirect, and you need to place this rule before the routing rule that you have. So everything should look roughly like this:
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteBase /
RewriteCond %{QUERY_STRING} ^course_id\=([^&]+)\&format\=([^&]+)$
RewriteRule ^/?books/course$ /course/%1/format/%2 [R,L]
#Source: http://codeigniter.com/user_guide/general/urls.html
#Removal of index.php
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /index.php?route/$1 [L]
</IfModule>
You'll need to tweak the paths to make sure they match what you are actually looking for.
To both redirect the browser and internally rewrite back to your original URL, you need to do something different.
First, you need to make sure all of your links look like this: /course/CC100/format/XML. Change your CMS or static HTML so all the links show up that way.
Then, you need to change the rules around (all before your codeigniter routing rule) to be something liek this:
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteBase /
# redirect browser to a URI without the query string
RewriteCond %{THE_REQUEST} ^(GET|HEAD)\ /books/course/?\?course_id=([^&]+)&format=([^&]+)
RewriteRule ^/?books/course$ /course/%2/format/%3? [R,L]
# internally rewrite query string-less request back to one with query strings
RewriteRule ^/?course/([^/]+)/format/([^/]+)$ /books/course?course_id=$1&format=$2&submit=Submit [L]
#Source: http://codeigniter.com/user_guide/general/urls.html
#Removal of index.php
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /index.php?route/$1 [L]
</IfModule>
I'm not going to address the misunderstanding already addressed pretty well in the other answer and comments, and I can't speak for CodeIgniter specifically, but having given their URL routing docs a quick skim, it seems pretty similar to most web frameworks:
You probably just want to direct all traffic (that doesn't match physical files) to the frontend web controller (index.php) and handle the URL management in CodeIgniter's routing, not a htaccess file.
To do that, your htaccess could be as simple as:
<IfModule mod_rewrite.c>
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule .* index.php [QSA,L]
</IfModule>
This, as I said, will redirect any traffic that doesn't match an physical file such as robots.txt or an image to your index.php.
Then, using the routing as described in the docs (http://ellislab.com/codeigniter/user-guide/general/routing.html) you can take in parameters and pass them to your controllers as you see fit, there is no need to 'convert' or 'map' anything, your URL's don't need to resolve to /?yada=yada internally, based on your routing rules CodeIgniter can work it out.
You'll need wildcard routes such as this from the docs:
$route['product/:id'] = "catalog/product_lookup";
A rough example of what yours might end up looking like would be something like:
$route['course/:id/format/:format'] = "course/something_or_other_action";
If I'm understanding you correctly, you might be over-thinking it. I have something similar in my own code.
I have a controller named Source. In that controller, I have the following method:
public function edit($source_id, $year)
{
# Code relevant to this method here
}
This produces: http://localhost/source/edit/12/2013, where 12 refers to $source_id and 2013 refers to $year. Each parameter that you add is automatically translated into its own URI segment. It required no .htaccess trickery or custom routes either.
I am trying to get url from:
192.168.0.1/movie-page.php?id=123
to:
192.168.0.1/movie/movie-name
or even (for now):
192.168.0.1/movie/123
I've simplified it by using this url (to get something working):
192.168.0.1/pet_care_info_07_07_2008.php TO 192.168.0.1/pet-care/
my .htaccess file:
RewriteEngine On
RewriteRule ^pet-care/?$ pet_care_info_07_07_2008.php [NC,L]
What am I doing wrong? I've tried many combinations but no luck and my patience is running out...
I am running this on my local NAS which should have mod_rewrite enabled by default. I have tested .htaccess by entering random string in .htaccess file and opening the page, I got 404 error. I assume this means that .htaccess is being used since the page stops functioning if the file is malformed.
If you want to rewrite:
192.168.0.1/movie-page.php?id=123 too
192.168.0.1/movie/movie-name or 192.168.0.1/movie/123
Then you would do something like, but will require you manually add a rewrite for any new route (fancy url) you want, and eventually you may want your script to create routes dynamically or have a single entry point to sanitize:
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^movie/([a-zA-Z0-9-]+)$ movie-page.php?id=$1 [L]
So a better method is to route everything through the rewrite:
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php?route=$1 [L,QSA]
Then handle the route by splitting the $_GET['route'] with explode()
<?php
//192.168.0.1/movie/movie-name
$route = (isset($_GET['route'])?explode('/',$_GET['route']):null);
if(!empty($route)){
//example
$route[0]; //movie
$route[1]; //movie-name
}
?>
You want something like this:
RewriteRule ^movie/([0-9]*)$ /movie-page.php?id=$1 [L,R=301]
That will give the movie ID version with a numeric ID.
I use the code below to basically go to my pages. How it works is I put index.php?req=pagename and it will check my protected folder to see if the file is there if it is then it goes there. I need a mod rewrite so that it doesnt show all that index.php?req=pagename and just shows /pagename
require_once("protected/header.php");
if (isset($_GET['req'])) {
$req = $_GET['req'];
} else {
$req = "overall";
}
require_once("protected/$req.php");
require_once("protected/footer.php");
Your code allows any php file (barring safemode/open_basedir restrictions) to be parsed and executed. You need to escape that input first, even if it's something as rudimentary as removing slashes, tildes and periods.
As far as rewrite goes, simply create a .htaccess file in your document root along the lines of:
<IfModule mod_rewrite.c>
RewriteEngine On
#RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ /index.php?req=$1 [QSA,L]
</IfModule>
You will have to use POST instead of GET if you want a clean dynamic url. Your question though doesn't make much sense.
